Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2018-0026009 filed on Mar. 5, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a pipette unit for cosmetics and a cosmetic container having the same, and more particularly, to a pipette unit for cosmetics having a brush tip between a pipette and a brush member and a cosmetic container having the same.

Description of the Related Art

In general, as a method of using liquid contents such as cosmetics, which is preferable to use a small amount of eye cream and the like at a time to use a precise quantity, conventionally, a method of individually packaging the contents in the form of a capsule or the like by an amount to be used for each use time was used.
However, such an individual packaging method has a problem in that it is extremely inefficient because a relatively large amount remains in the capsule even after the user uses the contents.
In order to overcome the problems s of such an individual packaging method, after the contents are accommodated in the container, it is designed a configuration of extracting the contents every use by using an extracting means having a general pipette or a syringe structure or using an extracting means having a configuration of a push pump.
In the case of the extracting means having a general pipette structure, the amount of suction and extraction varies depending on the degree of pressing a pressing portion made of rubber by the user.
In the case of using the extracting means having the syringe structure, when considering that a very small amount of about 1 ml is used, a diameter of the syringe is made extremely small or the stroke of a syringe piston is made extremely small. In addition, in order to extract the contents, the piston of the syringe is pulled out to suck the contents, and then the piston of the syringe is pushed again to extract the contents.
In the case of the extracting means having a configuration of a push pump, a certain amount of contents may be extracted whenever simply pressing a button. However, the structure is relatively complicated because a structure for forming the inside and the outside of the pump is configured by including a button, an inlet, an outlet, a spring, and a valve structure.
On the other hand, since the conventional pipette has an inconvenience in applying the contents to the skin or diluting the contents with other solvents on the structure, an improvement measure is required.
The above-described technical configuration is a background technique for assisting the understanding of the present invention, and does not mean a conventional technology widely known in the art to which the present invention belongs.

SUMMARY OF THE INVENTION

Therefore, an object of the present invention to achieve the present invention is to provide a pipette unit for cosmetics and a cosmetic container having the same capable of improving inconvenience of applying cosmetics to the skin or diluting the cosmetics with other solvents.
According to an aspect of the present invention, there is provided a pipette unit for cosmetics including: a brush member provided at an end of the pipette; a brush tip coupled to the end of the pipette so as to be disposed inside the brush member and allowing the cosmetics to be introduced or extracted into or from the pipette; and a brush fixing member coupling the brush member to the end of the pipette, in which an expansion portion is provided on the upper side of the brush member and the extension portion is disposed between the end of the brush tip and the end of the brush fixing member and coupled to the end of the pipette with the brush tip by the brush fixing member.
The brush tip may include a fixing portion disposed between the end of the pipette and one side of the brush member; and an extension portion extended from the fixing portion to the other side of the brush member and in contact with the inside of the brush member.
The extension portion may be provided to be inclined so that a width of a region disposed at the end of the pipette is greater than that of a region disposed at the other side of the brush member.
The expansion portion of the brush member may be provided by heating.
According to another aspect of the present invention, there is a cosmetic container including: a cap portion coupled to a container body; a button portion coupled to the cap portion; a pipette of which one side is coupled to the button portion and the other side is extended to a bottom portion of the container body; a brush member coupled to the other side of the pipette; a brush tip coupled to the end of the pipette so as to be disposed inside the brush member and allowing the cosmetics to be introduced or extracted into or from the pipette; and a brush fixing member coupling the brush member to the end of the pipette, in which an expansion portion is provided on the upper side of the brush member and the extension portion is disposed between the end of the brush tip and the end of the brush fixing member and coupled to the end of the pipette with the brush tip by the brush fixing member.
According to the exemplary embodiments of the present invention, it is possible to efficiently sucking cosmetics by preventing a brush member from being collected when the cosmetics are sucked into the pipette by a brush tip disposed between the pipette and the brush member.
Further, it is possible to conveniently apply the cosmetics to the skin by the brush tip and the brush member and dilute the cosmetics with other solvents.
Further, it is possible to easily couple the brush member by an expansion portion provided in the brush member and stably maintain coupling force even during use.
